In 1991 Nintendo hosted a second Nintendo World Championship but toured 58 college campuses so they called it the Campus Challenge. Nintendo made a special cartridge just for this event that had Super Mario 3, PinBot, and Dr. Mario. After the competition was finished all of the cartridges were supposed to be destroyed, but in 2006 this cartridge appeared at the garage sale of an ex-Nintendo employee.

The auction started at $0.99 with no reserve but the price already up to $3,250. Where will it end up? We will be sure to update the VGPC price for Nintendo Campus Challenge 91 once the auction closes.

UPDATE:
The game sold for a record $20,100. A user on youtube posted a video showing the last two minutes of the auction as the price increased from $8,500 to $10,000 and then to $20,100 with 2 seconds left.

Congratulations on the sale of the world's most valuable rare video game! For those who weren't watching, the auction shot up from $8,500 to $20,100 in the last minutes of the eBay auction and some NES collector is now very happy!

That's awesome, I had never heard of this, or even new they went around holding competitions at campuses. I really feel like I missed out on a time in which I would have greatly enjoyed; hopefully gaming competitions make a major comeback, online is great, live is far more exciting.
